Driving light wiring

lazy rambler · Post by **lazy rambler** » Mon Jul 11, 2011 8:44 am

A couple of months ago I fitted some new driving lights to my bull bar but couldn't get them to work. A mate has told me that they don't work because I followed the instructions as SJ's have negative (-) earth. Is this right and if so how do I make them work.

ATM I have a wire going from the sidelights to a switch (earthed to bulkhead) a wire going from switch to relay (earthed to chassis) the relay has a wire going to battery positive (+) and another one going to the new lights.

follow this wiring diagram If you want the spots to come on with full beam

I want them on a switch, so not always on with the full beam lights

ah so you want them wired up in their own circuit then? if so......

Still couldn't get them to work so they are going on a independent circuit.

But as I'm rubbish with electrics I'm having a mechanic mate of mine do them.

Everyone's rubbish at electronics until they realise how easy most of it is. Even if you don't have a soldering gun, you can get away with chock block most of the time.

Or like this, on with high-beam or off altogether.........

That's how they are at the moment, but don't work. I've been told that this is because the SJ lights have a - earth and my lights have a + earth.

Electrics are easy

Especially on SJs!

Do you have a multimeter? If so, hold your main beam on "flash" (use an elastic band or something) and measure the voltage between the pins in the headlight plug.
If it's a positive numbers, then the red probe is going towards the +ve and the black the -ve
If its a negative number, then the black probe is connected to the +ve and the red the -ve

Connect relay pin 85 to the -ve, and pin 86 to battery positive, as shown in Dudleydo's diagram
